Zwift companion app Samsung S22 wont get past login

Hi new to zwift.
Zwift app running fine on my samsung S22. Have completed a couple of rides and no issues.

Downloaded zwift companion app opened app added login details and it freezes just a line running across top of phone as if its loading.

Checked app it gets to about 1mb of data and 1.2mb cache and just stays there.

Uninstalled and reloaded same. Trued maybe 10 times.

Have now tried on my Samsubg S20 and worked instantly, also tried on my iphone SE and again instant.

Any reason why it will not load on my S22?

Also unrelated but no joy with garmin HR monitor connecting to zwift amd ideas on one that will work connecting to zwift app using my S22
